No luck.
I soaked the PCB in alcohol and then let it air dry for 24 hours. I put it back together and still no start.
Some more info:
When I bought the car, the key remote didn't work, so I have always locked and unlocked it with the key in the door lock. Before this happened, the alarm would "beep" once when I lock the doors.
Now, when I lock it using the key in the door it beeps once with a brief pause, and then emits two more beeps. It does this every time I lock it.
The windows both go up and down fine and the top works. But when I turn the key to start it, nothing happens. I can hear things coming on when I turn the key and the radio and OBC all work.
Am I hosed?
